Plenoptic imaging systems are often used for applications like refocusing,
multimodal imaging, and multiview
imaging. However, their resolution is limited to the number of lenslets. In this
paper we investigate paraxial,
incoherent, plenoptic image formation, and develop a method to recover some of
the resolution for the case of a two-dimensional (2D) in-focus object. This
enables the recovery of a
conventional-resolution, 2D image
from the data captured in a plenoptic system. We show simulation results for a
plenoptic system with a known response and Gaussian sensor noise.
